I want a sine signal with variable frequency with frequency range 30- 150 Hz and amplitude should be constant. This signal is a second order run-up signal from an automobile engine.Can any one suggest me how to establish the variability in frequency term w.r.t time of the signal. sin(2*pi*f*t) both f & t are variable and dependent on each other
